Application March 4, 1957, Serial No. 643,715

1 Claim. (Cl. 299-72) This invention relates to a device for supporting lawn sprinkler nozzles. The usual lawn sprinkler nozzle of the set type throws water upwardly and outwardly about the nozzle. Such a spray is diicult to control over limited areas and is blown out of control by the wind.

The principal object of this invention is to provide a support for conventional set sprinkling nozzles which will support the nozzle in an elevated inverted position so as to direct the spray downwardly to vavoid wind disturbance, and to provide a support whereby the height of the nozzle above the lawn can be adjusted so that the downwardly directed spray can -be accurately regulated to cover a restricted area without requiring regulation of the water supplied to the nozzle.

With the use of this invention a set sprinkler can be set and supported to water accurately up to a sidewalk, curb, or building wall without wetting the wall o1' walk, and can be set to water narrow lawn strips without water waste and without it being necessary to regulate the water ow.

A further object of the invention is to provide a set nozzle support which will allow the user to approach the nozzle for setting purposes without danger of water damage.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efficiency. These will become more apparent from the following description. n

' In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in 4all views of the drawing and throughout the description.

In the drawing:

Fig. l is a perspective view of the improved lawn sprinkler nozzle support with the conventional nozzle removed;

Fig. 2 is a horizontal section looking downwardly on the line 2 2, Fig. l; and

Fig. 3 is a fragmentary side view of the upper extremity of the improved nozzle support, showing a conventional set-sprinkler nozzle in place thereon.

The improved nozzle support employs a vertical post or standard preferably formed from metal tubing, such as aluminum tubing. The lower extremity of the standard 10 is attened and sharpened to provide a chisel-like point 11 adapted to be forced into the lawn.

An inverted, dish-like foot plate 12 is xedly mounted on the standard 10 above the point 11 to provide a foot rest to facilitate forcing the point into the lawn and to provide a supporing base which will limit the amount of point insertion and to provide a brace-like supporting base for the standard.

The standard 10 is designed to support a bent water tube which is contoured to provide a medial vertical portion 13, a horizontal, rearwardly extending, lower intake extremity 14, and an inclined, forwardly and upwardly extending portion 15.

2,852,307 Patented Sept. 16, 1958 ICC The lower intake extremity 14 is provided with a female hose coupling 17 adapted to receive the male terminal coupling of a conventional garden hose, as indicated at 24. The inclined, upwardly extending portion 15 is provided at its extremity with a conventional male hose coupling 16 upon which any desired lawn sprinkler nozzle may lbe threaded.

The bent water tube is supported from the standard 10 by means of two clamping plates 18. The clamping plates are formed with semi-cylindrical terminal grooves 19, the concavities of the grooves of one plate facing the concavities of the grooves of the opposite plate to provide two clamping channels in which the standard 10 and the vertical portion 13 of the bent tube are received. The two plates can be drawn toward each other to clamp them to the standard 10 and the portion 13 by means of a clamp bolt 20 provided with a suitable wing nut 21.

The improved support is more particularly designed to support a set sprinkler nozzle ofthe type generally known as a lawn twin. Such a sprinkler is provided with two spaced-apart spray openings arranged to spray the water upwardly and outwardly in inverted coneshaped sprays when the sprinkler is resting on the lawn in its conventional position.

Such a nozzle is shown at 22 in Fig. 3. For use with this invention, the nozzle 22 is threaded onto the male hose coupling 16 so as to direct its spray (indicated at 23) forwardly and downwardly so as to cover an area directly in front of the standard 10. The size of the area covered can be regulated by loosening the clamp nut 21 and raising or lowering the nozzle by relative adjustment of the plates 18 on the standard 10 or by relative adjustment Abetween the vertical portion 13 of the bent tubes and the plates 18.

It can ybe seen that, since the water discharges from the nozzle in a conical spray, the area covered can be increased by adjusting the nozzle upwardly, and can bev decreased by adjusting the nozzle downwardly. Thus, accurate control can be had at all times without any adjustment of the water supply.

While a specific form of the improvement has been described and illustrated herein, it is to be understood that the same may be varied, within the scope of the appended claim, without departing from the spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent is:

Means for supporting a set-type lawn sprinkler nozzle in an inverted position comprising: an elongated standard; means for supporting said standard in a vertical position on a lawn; a water tube having a substantially straight medial portion, a substantially straight lower extremity extending rearwardly from said medial portion at substantially to the latter, and a substantially straight upper portion extending forwardly and upwardly from said medial portion at an incline of substantially 45; means securing the medial portion of said water tube to said standard and acting to maintain said medial portion in vertical parallel relation with said standard; a male hose coupling mounted on the extremity of said upper portion; a female hose coupling mounted on the terminus of said lower extremity; and a sprinkling nozzle mounted on said male hose coupling, said nozzle having an outlet directed forwardly and downwardly at a substantially right angle to the axis of said upper portion.
